EUGENE C. RICHARD, OF DETROIT, MICHIGAN, ASSIGNOR TO SARAH L. KNEELAND, OF LANSING, MICHIGAN GAS OR EXPLOSION ENGINE.

SFECIFIGAIION forming part of Letters Patent No. 791,501, dated June 6, 1905.

' Application filed December 7,1903. Serial No. 184,190.

This invention relates to improvements inv gas or explosion engines.

The ob ects of th1s invention are, first, to provlde an improved vaporlzer or carbureter for gas or explosion engines in which the fuel is all utilized and not wasted; second, to provide an improved vaporizer or carbureter for gas or explosion engines specially adapted for use with a throttle-governor; third, to provide an improved vaporizer or carbureter for gasengines which is simple and compact and not likely to get out of repair.

Further objects and objects relating to structural details will definitely appear in the detailed description to follow.

I accomplish the objects of my invention by the'devices and means described in the following specification.

The invention is clearly defined, and pointed out in the claims. I

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings,forming apart of this speci fication, in which a portion of the fly-wheel being broken away to show the arrangement of the governor mechanism. Fig. 2 is a detail vertical sectional view taken on a line corresponding to line 2 2 of Fig. 1. Fig. 3 is an enlarged detail sectional View taken on lines 3 3 of Figs. 1, 4, and 6. Fig. i is an enlarged detail sectional view taken on lines 4 4 of Figs. 3 and 6. Fig. 5 is an enlarged detail sectional view taken on a line corresponding to line 5 5 of Fig. 3, showing the details of the controllingvalve 0. Fig. 6 is an enlarged detail plan view of the vaporizer, the valve-casing E and the delivery-pipe E being removed. .Fig. 7

is an enlarged detail plan'view of the govcam a on the'hub of the gear a.

ernor mechanism and its connections to the valve.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar partsthroughout the several views.

Referring to the drawings, A is the frame of the base of the engine, which in this instance also serves as a storage for the liquid hydrocarbon. The crank-shaft B of the engine is mounted in suitable bearings A. The

pump C is connected to the storage-tank by the pipe f. The pump 0 is of the usual or any desired style and is provided with an up spring .9 is regulated by means of the collar 0",

is actuated by the pivoted lever 6, (see Fig. 2,) V

which carries a roller 1), adapted to engage the under side of the nuts 0 on the pump-rod.

These nuts are adjustable to regulate the stroke of the pump. Thelever b is actuated by the A roller 6 rests upon the cam a. The gear a is driven by the pinion a on the crank-shaft B. The gears a and a are properly proportioned.

The atomizer or carbureter proper consists of a main chamber D and a feed-chamber D therefor. A delivery-pipe C connects the pump to the feed-chamber. A passage connects the'chambers D D. The delivery of the oil from the feed-chamber to thevaporizing or carbureting chamber is regulated by the needle-valve 2', which is provided with a suitable knurl 41'.

The liquid hydrocarbon is desage opens into or is connected to the airpassage Across the top of the chamber as is a screen 0. The screen 0 is retained in position by the valve casing E, which is threaded into the top of the chamber D. The delivery-pipe E suitably connects the chamber D to the engine-cylinder. Air is drawn through the atomizing or carbureting chamber by the suction of the engine. A valve 6 is provided for controlling the same. (See Figs. 3 and 5.) A slanted partition plate or deflector in the bottom of the chamber D is provided to direct a considerable portion of the air passing through the carbureting-chamber into the passage In operation air is drawn through the atomizing or vaporizing chamber by the suction of the engine, and a portion of the air passing through the passage 1" into the passages 7" and j becomes saturated with and carries or dashes the liquid hydrocarbon into the mixing-chamber a" and against the screen 6, where it is met by the inrushing air, which is thereby suitably mixed therewith and drawn past the valve e into the engine-cylinder. The adjustment of the valve 0 regulates the amount of air drawn through the atomizer or earbureter. This adjustment is preferably automatically accomplished by means of suitable governor mechanism, preferably that described in my application for apatent filed concurrently herewith, although other suitable governor means might be used. The valve 0 is connected by the link G, which is secured to the arm 71/ on the shaft thereof, to the lever G, which is controlled by the governor mechanism, so that when the speed of the engine exceeds a predetermined point the governor acts upon the lever G and through its connections closes or partially closes the valve, thereby shutting off from the engine a portion of the supply of carbureted air, so that the force of the explosion is decreased or the explosion is entirely prevented. The speed of the engine is thus effectively regulated and this without a waste of fuel. The speed of the engine is also kept close to the predetermined rate.

An overflowpipe f is provided for the feed-chamber D. This pipe extends above the chamber D a short distance and is perforated or vented at f. (See Fig. 4.) This arrangement keeps the oil in the chambers D and D at about the same level.

' With the parts arranged as illustrated and described the liquid hydrocarbon is very effectively atomized and proper admixture with the air secured. The structure also prevents flooding of the engine. A waste of fuel is also prevented, the amount atomized being equal only to the demands of the engine. The speed of the engine is kept at about the point at which it is set to run. The structure is simple and compact and is not likely to get out of repair.

I have illustrated and described my improved vaporizer in the form preferred by me on account of simplicity and the economy of producing the same. I am, however, aware that it is capable of considerable variation in structural details without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
